Upgrading RAM to the maximum will ensure that your Computer is able to offer optimal, speedy performance. The Dell Precision Workstation T5500 (DDR3-1333MHz) (ECC) has 6 (6 banks of 1) RAM expansion slots, where you may install new memory, either by removing the existing installed RAM or adding memory to the free slot available. With additional DIMM slots to expand memory capacity up to 72GB2and an innovative chassis designed for flexibility, the Dell Precision T5500 can provide a highly scalable, cost-effective architecture with performance capabilities that can fundamentally change the way you work. Three channel memory architecture per processor with 1333 MHz and 1066MHz DDR3 ECC Registered DIMM memory.Up to 9 DIMM slots; 6 slots (2 per channel) on motherboard and additional 3 slots on optional 2nd processor riser card. The 2nd processor has an integrated memory controller which provides an additional 3 channels of memory bandwidth.

So I have a T5500 Precision that is showing LED's 3 and 4 on while booting. It's running one CPU. The service manual says it's a memory issue, but so far I switched out like 10 memory sticks and it still shows that issue. The highly scalable and compact chassis of the refurbished T5500 machine is designed for flexibility, supporting ECC Registered memory up to 72GB and a wide range of the latest and greatest graphics card with its two PCIe x16 Gen2 graphics slots.

Pengalaman menarik saat menginstall DELL Workstation T5500 untuk video editing. Secara default memory 4GB sudah terpasang dari vendornya. Computer berfungsi dengan baik. Namun karena dirasa kurang besar maka memory di upgrade ke 8GB, cukup besar untuk editing gambar dan video.

Stok yang ada di gudang adalah memory biasa , yang biasa dipakai untuk PC desktop. Namun ternyata pada saat dipasang dan computer dijalankan ada pesan error bahwa penempatan memory tidak sesuai. Terdapat dua bay memory yaitu yang di dalam main board dan di extended bay memory. Saat itu dipasang semua memory dengan kapasitas 2GB. Selanjutnya setelah penempatan memory dipasang dengan benar error lain timbul yaitu NON-ECC memory tidak bisa dipasang di computer ini. Lewat web DELL ditemukan jawaban dari semua permasalahan di computer workstation.

Berikut adalah petikan dari DELL untuk konfigurasi dan jenis memory untuk DELL Workstation T5500.

Your computer uses 1066 MHz and 1333Mhz DDR3 unbuffered or registered ECC SDRAM memory. DDR3 SDRAM, or double-data-rate three synchronous dynamic random access memory, is a random access memory technology. It is a part of the SDRAM family of technologies, which is one of many DRAM (dynamic random access memory) implementations, and is an evolutionary improvement over its predecessor, DDR2 SDRAM.

The primary benefit of DDR3 SDRAM is its ability to run its I/O bus at four times the speed of the memory cells it contains, thus enabling faster bus speeds and higher peak throughputs than earlier technologies. This is achieved at the cost of higher latency. Also, the DDR3 standard allows for chip capacities of 512 megabit to 8 gigabit, effectively enabling memory modules of maximum 16 gigabyte in size.

DDR3 memory comes with a promise of a power consumption reduction of 30% compared to current commercial DDR2 modules due to DDR3’s 1.5 V supply voltage. This supply voltage works well with the 90 nm fabrication technology used for most DDR3 chips. Some manufacturers further propose to use “dual-gate” transistors to reduce leakage of current.

The main benefit of DDR3 comes from the higher bandwidth made possible by DDR3’s 8 bit deep prefetch buffer, whereas DDR2’s is 4 bits, and DDR’s is 2 bits deep.

Memory Modules

Supported Memory Configurations

Memory Subsystem

The memory subsystem consists of three DDR3 memory channels attached to each processor. All single-processor configurations have six DIMM slots (two per channel) attached to the primary processor located on the system board. Dual-processor configurations require an optional riser card that contains the secondary processor and the DIMMs associated with the secondary processor. There are six DIMM slots on the riser, for a total of twelve DIMMs in the system.

Memory Slots

There are six memory slots on the system board. The slots are numbered DIMM1 through DIMM6. DIMM1 is furthest from the processor.

In addition, the dual-processor riser features three additional memory slots. The slots are numbered DIMM1 through DIMM3. DIMM1 is furthest from the processor.

Memory Population Rules

Your computer requires DIMMs within a channel to be populated starting with the DIMMs farthest from the processor first. This means the DIMM slots 1, 2 and 3 must be populated before DIMM slots 4, 5 and 6. In addition, when populating a Quad-rank DIMM with a Single- or Dual-rank DIMM in the same channel, the Quad-rank DIMM must be populated farthest from the CPU.

To maximize available memory bandwidth, DIMMs within a configuration should generally be spread across as many channels as possible before populating multiple DIMMs per channel. The population guidelines below help to achieve this.

Single CPU configurations (6 DIMM slots on MB)

• If configuration contains DIMMs of all the same size, populate in the following order: DIMM1, DIMM2, DIMM3, DIMM4, DIMM5, DIMM6
• If configuration contains DIMMs of mixed sizes, populate the larger DIMMs first. For example, for a 4GB configuration consisting of one 2GB DIMM and two 1GB DIMMs, the population would be DIMM1=2GB, DIMM2=1GB, DIMM3=1GB, DIMM4=empty, DIMM5=empty, DIMM6=empty.

Dual CPU configurations (6 DIMM slots on MB plus 3 DIMM slots on Riser)

T5500 Memory Slots App

• If configuration contains DIMMs of all the same size, populate in the following order: MB_DIMM1, Riser_DIMM1, MB_DIMM2, Riser_DIMM2, MB_DIMM3, Riser_DIMM3, MB_DIMM4, MB_DIMM5, MB_DIMM6.
• If configuration contains DIMMs of mixed sizes, populate the larger DIMMs in the Riser.
